Application filed October 11, 1919. Serial No. 330,097.

This invention relates to means for adjusting a moving picture film with relation to the window of a projector so that the picture may be properly framed upon the screen. I

The proper adjustmentmay be effected by observing the relation of the picture on the film to the window. The projector light is too intense for this purpose and when it is extinguished the ensuing darkness prevents the making of the desired observation.

It is the ob'ect of the present invention to provide a lig t whereby the framing observations as indicated can be accomplished.

.This may be accomplished by dimming the projecting light or by rovidin an auxiliary light of less intensity for illuminating the window during the framing observations.

Other and ancilliary objects of the invention will appear hereinafter.

Inthe accompanying drawing, which illustrates the invention, is shown a side elevation of a screen and moving picture projector, theflatter being shown partly in section. g

Referring to the drawings, the apparatus comprises. a screen 1 on'which the pictures are exhibited and upon which the light rays (indicated by dotted lines broken away at.

the centre to bring the drawing within the compass of the sheet) are projected by means of suitable projecting ap aratus having a lamphouse 2 within which are an electric arc lig t 3 of high intensity for'projecting the ictures upon the screen, and also within the amp house is an electric incandescent lamp 4 of'much less intensity than light 3 and suitable for illuminating the window so that adjustment of the film pictures may be effected. The lamp 4 may derive its current from any suitable source in a well known manner as may also the light 3 as is. well understood, and the lenses, film handling devices, shutter and other parts of the apparatusmay be of any of the suitable constructions well known in the art.

' When a film is to be adjusted in the apparatus, the lamp 4 is lighted and the arc 3 extinguished. A light of suitable intensity is thus provided whereby the desired observation can be made in adjusting the film so as to bring the picture into proper relation with the projector window. This adustment having been effected, the light 3 may be lighted and the lamp 4 preferably extinguished, the film started in operation and the exhibition be proceeded with.

said projecting apparatus, of less intensity than said projecting light for illuminating the projector window.

2. moving pictures comprising a projecting light and an auxiliary light upon the interidr o thelamp house of said projecting apparatus, of less intensity than said projecting light for illuminating the projector window.

3. Amoving picture projecting ap tus including a rojecting light and an aiiii i liary framing lig t within said apparatus and of less intensity than said projecting light for illuminating the projector window sov as to render the pictures on the film easily discerniblev for facilitating the framing operation.

In testimon whereof I have signed this specification t is th day of August, 1919.
